PREFACE The textbook was formerly titled Quality Control—Eighth Edition. It is re-titled as Quality Improvement—Ninth Edition to reflect the concept of improvement rather than control. This manual has been published to simplify the instructor’s tasks of developing learning activities and evaluating performance. It is based on the experience of the author and is meant to serve as a guide. Each instructor will need to modify this information for the particular course objectives and the ability level of the students. For those teachers who are familiar with the Eighth Edition of the textbook, information on the major changes to the Ninth Edition is provided. This information should simplify the transition to the latest edition. A typical course outline for a three-semester hour course is shown on Page 2. The learning activities are based on 45 class meetings of 50 minutes each. Since it is difficult for the average student to cover all of the material in a typical three-semester hour course, this outline concentrates on the basic statistical aspects of quality improvement. The instructor may wish to substitute Management and Planning Tools for Reliability. If a course in statistics is a prerequisite, the instructor may include Experimental Design and Taguchi’s Quality Engineering. Solutions for the problems start on Page 3. The author has found it advantageous to post the solutions. This action allows students to determine if their methods and answer are correct. Typical multiple-choice test questions are given and an asterisk indicates the correct answer. These questions can be modified in a number of ways depending on the creativity of the instructor. Answers to test problems are also given. Since the tables in the body of the text and in the Appendix are needed to solve the problems, an open-book type examination should be considered. The instructor may also consider providing copies of the tables and using a closed-book format. Regardless, the multiple-choice questions can be given in the closed-book format. The author has found that allowing the students 3x5 cards for formulas and other information is a great learning experience.

Major Changes to the Ninth Edition Chapter 1 1. Deleted Historical Review and Metric System. 2. Deleted the section on RESPONSIBILITY FOR QUALITY. 3. Added a section on QUALITY IMPROVEMENT TOOLS, with a brief description of those non-quantitative ones that are not covered in the text. 4. Deleted COMPUTERS AND QUALITY CONTROL. 5. Added COMPUTER PROGRAM. 6. Modified Exercise 2 and eliminated Exercises 3 and 4. Chapter 2 1. All previous information deleted 2. Much of the problem solving information moved to Chapter 3. 3. Chapter re-titled Lean Enterprise with all new information. Chapter 3 1. All previous information deleted. 2. Pareto Diagram, Cause and Effect Diagram, Check Sheet, and Process Flow Diagram moved to Chapter 4. 3. Chapter re-titled Six Sigma. 4. Statistical Aspects moved from old Chapter 5. Chapter 4 1. All information in old Chapter 4 becomes Chapter 5 2. Chapter is titled Statistical Process Control (SPC) and consists of Pareto Diagram, Cause and Effect Diagram, Check Sheet, and Process Flow Diagram. 3. Other elements of SPC are covered in subsequent chapters. Chapters 5, 6, 7, 8, 9, and 10 1. The basic change is to the number. Chapter 4 becomes 5, 5 becomes 6, 6 becomes 7, 7 becomes 8, 8 becomes 9, 9 becomes 10. 2. Gage control in Chapter 7 has been modified. Chapter 11 1. Old Chapter 10, Acceptance Sampling Systems is deleted and the number sequence is correct with no change to Chapter 11, Reliability. .Chapter 12 1. No change. Chapter 13 1. New chapter titled Experimental design. Chapter 14 1. New chapter titled Taguchi’s Quality Engineering.
